crucible

v0.1.0

Hard gates for the scientific method — pre-registration lock, computed sample-size, and a blind independent judge, enforced as gates the study pipeline refuses to pass. The deterministic core enforces the gates on any harness; on Codex the extra PreToolUse/Stop hooks degrade to advisory.

Included Skills1

crucibleskills/crucible/SKILL.md

Run a scientific study that is actually SOLID — pre-registered, adequately powered, and blind-judged — so the conclusion is defensible and whatever you build on top of it isn't built on sand. Use when the user wants to run an experiment, A/B test, ablation, eval, or comparison and have the result HOLD UP. crucible enforces the three disciplines an agent skips (pre-registration, sample size, blind judging) as gates the pipeline refuses to pass.
